SG3525 LM358 High Frequency Inverter Driver Board 12V-24V

The SG3525 LM358 High Frequency Inverter Driver Board is a compact, high-current PWM control module designed for driving high-power MOSFET and IGBT stages in DC-AC inverters and switched-mode power supplies (SMPS). Built around the industry-standard SG3525A voltage-mode PWM controller IC paired with an LM358 dual operational amplifier, this board delivers stable dual-channel complementary square-wave gate drive signals. Its integrated discrete totem-pole transistor driver stage delivers substantial peak sink and source currents, allowing it to charge and discharge high-capacitance power transistor gates rapidly without external buffer circuits.

Featuring an onboard precision multi-turn trimmer potentiometer, this driver board allows seamless frequency tuning between 20 kHz and 50 kHz to match your specific ferrite transformer resonance and switching requirements. The integrated LM358 op-amp stage provides precision overcurrent sensing, undervoltage protection, and fast shutdown feedback to safeguard your power MOSFETs during load spikes or short circuits. Compatible with 12V to 24V DC systems, it is the ideal drop-in driver solution for pure sine wave front-end stages, modified sine wave inverters, DIY high-voltage step-up boosters, and ultrasonic power generators.

Features:

• Precision PWM Generation: Powered by the SG3525A controller IC to ensure stable frequency and symmetric dual-channel drive output.
• High-Current Totem-Pole Drive: Integrated discrete transistor output stage drives multiple parallel power MOSFETs or IGBTs with ease.
• Adjustable Switching Frequency: Onboard multi-turn precision potentiometer allows precise frequency adjustment from 20 kHz to 50 kHz.
• Built-in Circuit Protection: Utilizes an onboard LM358 dual op-amp for real-time overcurrent sensing, shutdown protection, and feedback control.
• Wide Input Voltage Range: Operates reliably across a 12V to 24V DC power supply, ideal for standard battery bank systems.
• Standard 8-Pin Header Interface: Convenient single-row header pin layout enables clean vertical plug-in integration onto main power boards.
